When I was shooting 22 smallbore rifle matches winning some occasionally outscoring USA Olympic team members, cleaning the barrel after 50 to 60 shots was the norm for everyone.
Best accuracy was with Lapua, Eley or RWS made before 1980. That's when an explosion at the Lapua plant caused by bad primer mix. Eley was tasked to make a safer formula for all brands at the expence of less accurate ammo and shorter barrel life; 30,000 rounds versus 50,000. All USA prone records set before then still stand.
